TRUCK FOR AGRIGULTURAIF IMPLEMENTS.

Application filed ui 16,

To all whom it may concern:

Be it known that 1, JOHN H. EMERT, a

citizen of the United States, residing at 1 Peoria, in the county of Peoria and State of Illinois, have invented certain -new and useful Improvements in Trucks for Agricultural Implements, of which the" following is a specification.

This invention has reference totrucks and has for its object to provide a truck to be used in connection with agricultural implements, such as disk harrows, harvesters and binders, etc, for supporting the weightof the forward connections of such machines and draft appliances and thereby relieve the animals of such weight.

The invent-ion consists essentially of an axle capable of being oscillated in two different directions; horizontally, for steering the machine in different directions and vertically so that the truck will accommodate itself to the uneveness of the ground. A 5

steering tongue is providedand so connected with the axle that the axle may be swung from right to left or vice versa and. also up and down.

That the invention may be-more fully'understood, reference is had to the accompanying drawings, forminga part of the description, in which Figure 1 is a greatlyreduced side elevation of a truck embodying my improvements; Fig. 2 is an enlarged vertical and transverse section as the same would appear if taken on the line 22 of Fig. 1; Fig. 3 is a vertical longitudinal section of the truck, on the same scale as Fig. 2.

Like numerals of reference indicate corresponding parts throughout the figures.

The stub-tongue is designated A. This is the tongue which is attached to and extends forwardly from the implement, and is in- Specification of Letters Patent. Patented Sept, 10,1912, 1910; Seria1No.572,367.

will cause the axle togalso, turn in asimilar direction. 7

1 denotes the axle, said axle being a bar, the body of which is preferablyrectangular in cross-sectionand.having the; wheel carrylng spindles 2, to support the? wheels 3, shown in dotted'lines in" Fig. 1. The axle 1 is carried through a casting 4 which 1s provided with the centrallydisposed bearing portion a from which extend'i'n opposite directions the spaced and parallelbars 5,"terminat ing at a point short of the inner ends of the wheel spindles 2. The body of the axle lies between the bars 5 and adjacent thereto which serve to strengthen the axle .1 and relieve the axle from unnecessary strain 1 when turning. The connection between the axle 1 and bearing portion 4 of the casting 1- comprises a pin or bolt 6 passing transf versely through the axle, see Figs. 2 and 3, Q and sejcured in the bearing portion 4 The opening Tinthe axle through which the bolt (ipasses is sufficiently large sothat there which is further. relieved by the fulcrum portion 8 in the upper wall of, the bearing portion 4 against which the upper surface of the axle bears and on which the axle will oscillate in a vertical plane, so that the axle will accommodate itself to the unevenessof the ground. The fulcrum portion 8 ismerely a depending enlargement, as shown inFig. 5 2 having a convex face on which the axle will ride, the bolt or pin 6 serving only to hold the axle in operative position. Theto 3 portion of casting 4 extends forwardly an rearwardly of its bearing portion 1, as at 9 and-10,. and the upper surface of said portions 9 and 10 converge upwardly toward each other as at 11 and 12, presenting ini clined surfaces in opposite directions which unite or merge into a short vertical stud or pin 13. The function of such inclined surfaces and stud of .pin will be further. ex plained. i I

14: denotes a casting supported above the casting 4, having the forwardly and, rearwardly extended base portions 15. and 16,

similar to the portions 9 and 10 of the casting 4, and bolted thereto by bolts 17, see Fig. 1. The under face of the casting 14 is chan neled out, as at 18, see Fig. 2 to receive the casting 4 in manner shown, the upper wall of the channel poltion 15 being beveled or. inclined inwardly and downwardly as at 19,

starting from the front end and terminating cal wall 21. When the casting 14 is bolted on the casting 4, the inclined faces 9 and 15 j of the respective castings converge toward each other from the forward end, forming a chamber or recess 22 having vertical side walls and upper and lower inclined walls, and the inclined faces 12 and '20 of said castings 4 and 14, diverging as they do from a pointcoincident with the stud 13 to the rear end of the castings, form a chamber or recess 23, similar to the chamber or recess 22. The-functions of such chambers or recesses will be further explained.

The casting 14 has a short vertically disposed projection 24, preferably cylindrical in shape which serves as a base for a centerpin projecting axially therefrom and above the same, and also as a support for a similar projection or bearing portion 26 depending from a casting 27, which has the forwardly and rearwardly ex-tended tongue bearing portions 28 and 29. The pin 25is securely fixed in the proiection 24 of the casting 14 is loosely carried the casting 27, to allow for turning the casting 4 and 14 and the pin 25 in the bearing 26, as will more fully appear.

The stub-tongue A extends longitudinally of and across the portions 28 and 29 of the casting 27, being bolted thereto as at 80 and 31, and said tongue near the forward end of the portion 28 of the casting 27 is carried between ears 32 attached to said casting 27, and secured thereto by a transverse bolt 33. The parts are braced by a brace-bar 34 bolted to the underside of the stub-tongue and extending downwardly and forwardly having its front end connected to the lower face of the bearing portion 4 of the casting 4, preferably by forming a depending stud 35 on the lower face of the casting 4 over which the end of the brace-bar 34 is carried and the parts held in operative position by a bolt 36. In this way the turning of the casting 4 and axle 1 are not aifected by the brace-bar connection 34.

To the lower face of the steering tongue B is secured a strap 37 which is carried downwardly and rearwardly from said tongue and provided with the horizontal rear extension 38, which is operatively con nected with the castings 4 and 14 in the chambers or recesses 22 and 23. The strap 37 is provided with a perforation 39 in its horizontal extension 38 which is fitted over the pin or stud 13 of the casting .4, before securing the casting 14 in place. When said casting 14 is fastened in place, it will be observed that the pin or stud 13 will prevent the strap 37 from becoming disconnected from said stud or pin 13, but that the strap 37 or its extension 88 may oscillate up and down, owing to the inclination of the matching walls 11 and 19, and 12 and 20 of the castings 4 and 14, which will permit of vertical oscillation of the steering tongue B, suflicientfor all purposes. The strap 37 fits easily in the chambered portion 18 of the casting l4, and its opening or perforation 39 is "sufficiently large to allow the strap to oscillate on the pin or stud 13, in the manner explained. The steering tongue B is oscillated from side to side through the connection of the strap 37 between said tongue and the castings 4 and 14, the strap bearing against the sides of the casting 14 causing said castings 14 and 4 and the axle 1 to be turned with the pivot-pin rotating in the bearing 26 of the casting 27. To prevent twisting of the strap 37 when turning the axle 1, I provide the strap or bar 40 secured to the tongue B which, at its rear end is socured to a curved bar 41 having an elongated slot 42 through which is carried the bearing 26 of the casting 27, to allow the bar to have movement transversely of the bearing 26, when the tongue B is raised or lowered.

The truck as described is serviceable in connection with harvesters and binders and disk harrows where a truck has special advantages, and may be used advantageously in connection with other and various types of farm implements. The steering tongue has the advantage of being capable of being raised and lowered and the axle, in addition to being swung from side to side by said steering tongue is also adapted to accommodate itself to the unevenness in the ground.
